Title: Method for discriminating the type of disk
Inventor: NAKAYAMA TAKESHI
IPC: G11B19/12
Filed: 1991-10-25
Abstract: PURPOSE:To discriminate the type of a built-in disk according to the comparison result with the set time by reading the time information saved in the disk. CONSTITUTION:When a disk 2 is loaded, the light beam is irradiated to the read-in area 22 of a disk by a pickup 4 which receives the reflection light. An electric signal based on this is inputted to an ATIP reproduction circuit 5, thereby analyzing the ATIP information. A discrimination circuit 6 compares absolute time Tr with specific time Th recorded on the disk 2 shown by an ATIP reproduction signal. In the case of Tr<Th, the size of the disk is 8cm. In the case of Tr>Th, the size of the disk is 12cm. The result of discrimination is sent to the control system and the recording and reproduction control according to the type of disk is performed.

Abstract: PROBLEM TO BE SOLVED: To enable obtaining at the same time, wiring trenches different in depth with one a time trench wiring work, by making wiring width of different wiring trenches different and changing depth of the different wiring trenches by using a microloading effect at trench wiring work. SOLUTION: An interlayer film 3 composed of SiN(silicon nitride) is formed on an insulating film 1 by CVD. After resist is coated, exposure and development are performed, and a resist pattern is formed. Trench wiring work by etching and resist elimination are performed in the condition in which the wiring widths of a wiring trench 31A and a wiring trench 31B are set so that the condition that the etching rate at the time of etching work of the wiring trench 31A is reduced to the etching rate at the time of etching work of the wiring trench 31B by a microloading effect is satisfied. Then the wiring trench 31A and the wiring trench 31B different in depth are obtained. As a result, various kinds of wiring designs are made possible.

Title: Multiplex broadcast receiver
Inventor: KATSUKI KIYOSHI
IPC: H03J5/00
Filed: 1993-10-13
Abstract: PURPOSE:To allow a listener to hardly take notice of sound interruption by setting a check interval at random with a random number when all alternative frequency(AF) stations given by an AF list are checked sequentially. CONSTITUTION:A controller 14 checks the reception level of a broadcast wave when a broadcast station of a frequency not present is received. When a detection level is lowered to a level set as an AF check start level, a random number generating routine generates random numbers within a predetermined range. Then as an interval time at random corresponding to the random number elapses, a mute circuit 6 is set ON to mute a voice signal and the check of an AF station is started. When the station is an AF station based on a station dated signal, the frequency and the reception level are stored in the predetermined area of a data memory 17. When the check for all the AF stations is finished in this way, the processing restores to the first step.

IPC: B41J29/13
Filed: 1999-09-30
Abstract: PROBLEM TO BE SOLVED: To provide a lock mechanism, which has small numbers of components and can be assembled easily and of which the components are prevented from abruptly slipping off from the assembly positions. SOLUTION: A lock mechanism 22 is constituted by only fitting two components of an operating stem main body 24 and a coil spring 29 to a movable member 15 or a fixed member 13 where a retention groove 23 is formed, and thus the number of components is lessened. The lock mechanism 22 can be assembled easily, by inserting the operating stem main body 24 and the coil spring 29 into the retention groove 23 and by hitching a stopper pawl 26 of the operating stem main body 24 on a hitch part 27. Since deflection of a flexible part 25 to a position, where the stopper pawl 26 disengages from the hitch part 27, is obstructed by the coil spring 29, the operation stem main body 24 and the coil spring 29 are prevented from abruptly slipping off from the retention groove 23.

Title: Semiconductor device
Inventor: ITO KIYOO
IPC: H01L29/792
Filed: 1998-10-02
Abstract: PROBLEM TO BE SOLVED: To obtain a small size memory cell including the gain which assures the RAM operation by comprising a read transistor, a write transistor and a coupling capacitance for controlling a voltage of memory cell node. SOLUTION: A ternary level word voltage pulse is impressed to a word line WL. In the non-selecting mode, the read operation is performed while the write transistor QW is non-conductive. Therefore, the read voltage selected is lower than the threshold voltage VTW of the transistor QW. The write voltage is selected higher than the high voltage (VDD)+VTW or higher. A capacitor C shifts the voltage written into the memory node N to the negative side when the write operation is completed and the word voltage is changed to shift to the non-selecting condition. If a selection transistor is not provided, a memory cell can be selected and therefore reduction in size can be realized. A current flowing into the read transistor QR is converted to the voltage on the data line and thereby the signal voltage appearing on the data line is increased.

IPC: B62L3/04
Filed: 1993-10-15
Abstract: PURPOSE:To facilitate the change and replenishment of brake oil. CONSTITUTION:A reserve tank 37 for a rear brake is disposed inside and near the lower edge of a side cover 24a and above a master cylinder 28. An oil hose 36 is laid almost vertically across the reserve tank 37 and the master cylinder 28. A hose that can support the reserve tank 37 by its own rigidity is used as the hose 36 so as to enable the reserve tank 37 to self-support. At the brake oil filling time, there is thereby no need to support the reserve tank 37 by hands, nor need to remove body external covers. The change and replenishment of brake oil is therefore facilitated.

Title: Cryogenic freezing device
Inventor: FUJIMORI KANJI
IPC: F25B9/00
Filed: 1987-11-09
Abstract: PURPOSE:To provide a device which enables execution of continuous operation and effective utilization of refrigerant gas, by a method wherein an adsorber to remove impurity gas which solidifies in a range from an ordinary temperature to a liquid nitrogen temperature is installed, while a heat exchanger is mounted to the depressurizing line of the adsorber, and the depressurizing line on the downstream of the heat exchanger is returned to the suction side of a compressor. CONSTITUTION:Refrigerant gas, e.g., He gas, compressed by a compressor 1 passes a discharge line 11 and is fed to an adsorption circuit 2, in which impurity gas having a setting point in a range of from an ordinary temperature to the precold refrigerant temperature of a very low temperature freezer 3, e.g., a liquid nitrogen temperature, is removed. When an amount of impurity gas adsorbed exceeds the capacity of an adsorbent, adsorption and reproduction of adsorbers 21a and 21b are repeated. For example, while impurity gas is absorbed by the adsorber 21a side, reproduction of the adsorber 21b is effected. Inflow and reverse flow of refrigerant gas on the adsorber 21b side are rendered ineffective, refrigerant gas in a system is discharged through a depressurizing line 28, and a pressure is reduced for depressurization. In this case, an adsorption heat exchanger 8 is cooled by means of liquid nitrogen, slight impurity gas contained in depressurized gas passing through the exchanger 8 is adsorbed and removed, and refined He gas is returned to the compressor 1.
